All About Sharks
We have probably all seen the terrifying movie, Jaws, which left us debating whether we really wanted to enter into the waters for recreational fun. However, this flick was based more on horrific movie fun than real facts. Let’s check out the world of sharks to see if we can at least debunk the stalking man-eating trivia of Jaws.
There are 350 species of shark and they can range in size from small to humongous. They have lived in our oceans for around 350 million years. They have an acute sense of hearing and smell along with good eyesight. They use these senses to hunt their prey.
The shark is made up mostly of cartilage instead of bone. This makes it a powerful swimmer. And strangely enough their skin may look smooth, but it is actually so rough it can be used as sandpaper.
Our movie man-eating menace in Jaws was a Great White shark. It can be found in the cooler coastal waters throughout the world. This shark is the largest predatory fish in the world. It can grow up to 20 feet long (6 meters) and weigh around 5,000 pounds (2,268 kilograms). Its teeth are the perfect hunting weapon. It has 300 triangular serrated teeth that are arranged in rows. When the shark senses its prey it will come up from underneath and grab it with its powerful jaws.
Even though Jaws did depict the great white as a man-eater, attacks on humans are rare. Scientists believe when a shark “attacks” a human it is more of a sample-biting and not a full out attack. Though this can still lead to massive injuries to a human, the shark really doesn’t want to eat us. Its main diet is seal, sea lions, dolphins, turtles and fish.
One of the reasons sharks are so dangerous to their prey is their highly evolved sense of smell. They can detect one drop of blood in a million drops of water. Plus, they can hear a fish in the water up to a mile away.
Researchers have also been studying the shark and its healing properties. If a shark is wounded the gash will heal quickly and they rarely get tumors. So what is it about this mighty beast that keeps it healthy? Scientists believe the skin on the shark is always replacing itself, aiding in the speed of healing and the unlikelihood of infections.
Perhaps one of the reasons sharks are so deadly to their prey, is the fact that mother sharks do not nurture their young. Baby sharks (or pups) are born with many siblings and are immediately left on their own to survive. In fact, some mother sharks view their young as prey and will turn around and eat them. Less than half the pups make it to adulthood. They spend the first part of their young lives near the top of the water, hunting for small fish.
I hope we were able to shed some light on the life of a shark. They are truly fascinating creatures, so take some time to do further research, or check out an aquarium where you can see them in action.
